Application filed April 15, 1907. Serial No. 368,178.

To all whom. 'it 'may concern.;

lie ill lonjwn ilit l, lievi Qi'. Gmini., citizen ot the United States,residing at Chicago, in

.the county ot' Cool; and State of illinois, o have invented certain newand useful linpi'ovements in tollowing;A a specification.

.t'ly invention .relates to type-writing machina-s and has :pecialreference to that class ot imicliinesl employing a single laey secured.to a movable ffhar, the various printing` positions beineA regulated bymeans of an attached stylus.v

The chiot objects oi produce a type-writing iny invention are to ymachine of the class lated that will be .simple in its 1nech anism, easyto operate, and that can be readily understood and manipulated by anunskilled person.

Further objects are to' provide improved (s ior operatinpl the inlring`mechanism with a view to increase its eliieiency and :dui-ability; toifurnish a reliable and conveulentmethod ot handlingthe paper; to renderthe various parts durable, and to produce a machine oi such design andconstruc- -ticn that -it can be economically manufactured.

l accomplish the above and other important results by the employment ofthe ine- -chanical construction illustrated in the ac- '.companyingdrawings which form a part or' ythisspecication and in which:

a fragmentary view showing the bell the mechanism is supported and whichis 'furnished with feet'l, preferably formed with rubber to preventabrasion of the desk or table upon which the machine may be placed. Thisplate is provided with a pillar 14 formed integral therewith, and tothis is secured by screws 15 a bracket 16 the lower end ot which restsupon a shoulder 17 termed in the said pillar. The bracket carries ahorizontal trame arm 18, which is semi-circular in cross section asshown vin Fig. t?, to give rigidity' to the member Which supported atone end only by the bracket 16. iflxtending horizontally orwardfrom saidtrame arm 1S near each end are duplicate arms 1) which support atransverse cha acter bar 20. This bar is provided with registcringslots2l alongits front margin and upon the upper surface adjacentto saidslots are impressed a series of characters 22 disposed in two lines oneabove the other except where the characters represent the letters ot'the alphabet, when one character will stand tor both upper and lowercaseletters.

A type-bar frame 23 has rearwardly projectingr arms 24 which are pivotedto the extremities of the frame arm 18 by sh0ul The said frame23 is heldin its initial position by a spring Wire 26 having a portion of itslength coiled about the body ot ashouldered screw 27 which passesthrough an adjusting plate 28 and .engages a threaded hole in the framearm 18. Said plate is furnished with an ear 29 which engages the fixedend of the spring 26. The shoulder of the screw 27 holds the .plate fromturning and when said screw is loosened it permits the said plate to beturned on its center 27 by means of a handle 31 so that the resiliencyof said spring 26 may be increased or diminishedat will. The end 32 ofthe sprirfg` is received rina notch 33 in the underside of the type barframe. The transverse portion of said frame 23 isV Ll-shaped in crosssection and open at the,

end by gudgeons 37 which are journaled in brackets 3S secured to theunder side of said sliding plate byscrews Si). 4G. -Upon the undersurface of said type bar and formed integral therewith are the printingcharacstops 42 which permit the bar to oscillate in either direction toa sufficientextent to bring'thelines of printing type alternately into aposition vertically below the said centers. -t tension spring 43 issuspended at i its upper end to a yoke 45 secured by the screw 40. tothe plate the lower endv of sald spring being attached to' a radiallyextending arm 46`rigidly fixed to one of the bearings 37 ofthe type-bar.The upper end of said spring is located directly over the center ofoscillation of said bar, as'shown in Fig.7. The positions of the springat tachrncnts relative to the limitations imposed by said stops 42are.such that when either of the stops engages 'the underside of theplate the spring 43 will make traction upon that side ot' the center ofoscillation and tend to hold the bar in the position then occupied, oneof the lines of type being in the printing position which is shown, at a.Fig. 7 directly beneath the center of oscillation. Wvhen th'etype baris rocked so that the other stop is against the plate 35 bringing thesecond line of type into the printing position, the lower end of thespring 43 will swing past the center and exert tension from the oppositeside holding the parts in their `5 relative position until the bar isagain rocked upon its centers. The means employed for rocking the typebar to shift the position of the lines of type consists of two ke s 47,48, their stems 49 passing through ho es in the plate 35. bent at aright angle and engage holes in the ends of pins 5() projecting from theopposite i sides of the type-bar. One of said keys is normally u'p whenthe other is down, and to shift the bar itl is only necessary to depressthe key which is elevated. Upon the upper surface of said type-barplateis secured an operating key 5l fastened to said plate by screws 52. Thiskey is provided witha cap 53 from the rear of which projects a guidefinger 54 having its lower margin wedge shaped to insure its enteringthe proper slot when the key is depressed as hereinafter described. Fromthe front of'said key is a handle 55 which is grasped by the fingerswhen the key is operated.

A paper carriage is arranged transversely to the type-bar frame and iscomposed of a base plate 56 having end plates 5T formed l 62, 63, whichproject vertically `from the bed p plate l2 and has a' sliding fittherein, a collar i The lower ends of thestems arelv torni. consistingof a rubber roller64 mountj ed upon a shat't 65 is journaled in the endplates 57. the forward end projecting f through thebearing plate' 57 andcarrying l upon its extremity a thumb wheel G6 provided with a sleeve(37, the inner end of which carries a line-spacing ratchet G8. lie4tween said ratchet and the bearing plate 57 is located a pawl platetif) carrying a pawl tooth 7() which is adapted to engage the teeth ofsaid ratchet (38. The pawl tooth is held in engagement with the ratchetby a spring '7l attached at one end to an arm 72 extending from thepawl-plate (it), andat the other is secured to the carriage base at 73.The pawl plate has a line spacing lever 74 by means of which it can berocked upon the shaft 65, and is provided with a slot where'the saidshaft pierces it, to allow the g pawl tooth to ride over the ratchetteeth g when retracted by its spring. The rotation of said plate islimited by a stop pin 76 against which the arm 72 is held when theplate' is in its normal position. said pin engaging a shoulder 77 at thebase of the arm 74, when the latter is depressed, thus preventing thepawl from turning the platen farther than desired.

sheet ot' metal is secured at one edge to the upper surface of the baseplate 5o by rivets 7S), and passing beneath the platen is curved upwardand partly around the platen. its f free margin 80 lying closely againstthe face of the platen upon' which it exerts sutii'cient force toproduce some tension for the paper which is inserted between the platenand parallel with the platen and lies in contact therewith, and each endis bent downward at a right angle as indicated at 82. and the gextremities 83- bent in o posite directions to i he inserted in lugs 84died to the carriage position against the face of the platen by alocking lever 85 pivoted on the shaft 65 and furnished with a li 86which en ages the rod when in its initial position. l hefn it is desiredvto insert a `sheet of paper the lever 85 lifted until the rod 1sreleased and turned awayy from the' platen and the forward edge of thepaper inserted beneath. t The rod is then replaced and locked inposition by the said lever.

The carriage base plate 5G has a down turned flange 87 along its outermargin and l this flange and the lower edge of the ratchet plate 58 formguide ways which rest upon rollers 88. which project slightly above theupper surface ofthe bed plate through openings 89 therein, and arepivoted to brackets l 5)() by means of screws 91. A scale bar 92 isattach'ed to the side of the ratchet plate 58, the graduations 93 of thescale correspond 55 60'L serving as a stop. .t platen of the usual i ingwith the ratchet teeth. To the lug 62 is y base plate 5G. The -said rodis held in initial l A paper tension dip 78 vformed of a thin i saidtension plate. A guide rod 8l'is placed tired an indexY finger 94C torthe purpose Ot' locatingr the ,arriage relatively to the printing`point..

The under sidc ot' the type-bar frame Q3 is provided with adepending-lug 95 and directly beneath this lu` is located a spacinglever 00 the lower end ot which is attached to the middle ot a verticalarm 1)? one end ot which projects through a slot 98 in the bed plate 12and is pivoted to a tlange 91) by a `shouldered screw 100 upon whichsaid arm and attached lever rock. The said spacing` lever ismaintaiued'in an extended position by a spring 101 which is attached atone end to the upper end otl the arm 0T, and at the other to a fixedpoint on the. bed plate. The tree end ot the lever 11G is provided witha linger plate 102 and the downward movement ot s:,1id.lever is limitedby a stop finger 103 which strikes the bc'd plate 12; A spacing pawl arm10sL is pivoted to the upper end of the lever arm 0T by a pivot screw105 and has a finger plate 100 at the free end. Projecting from said armis a pawl tooth .107 adapted to engage Yhc ratchet teeth 58a, and uponthe opposite side is a projecting lng 10S which engages the inclinedupper margin 109 ot notch 11() formed in a Jost. 111 secured at 112.110the flange '951. i Then in the position shown in Fig. 0 the pawl arm10-1 is locked down by the said engagement. ot' its lug .108 with theinclined edge 109. The said lug also forms a stop torrthe lever 9o inits rearward movement. By depressing` the said lever either by theting-er or the action ot' the lug' when the type bar trame is moveddownward as hereinafter described,

the center 105 will be 'carried forward slitticiently to release thelug,- 10S and permit the pawl tooth 10T to ride over the teeth ot theratchet plate aslthe pawl arm is moved torward in unison with the arm97.

The lower part of the type-bar Jframe is provided with an opening 23directly over the platen to expose the type to t-hc action ot' aninking` roller 113 con'iposed of a suit,- able tibrous or absorbentmaterial saturated with an ink adapted to the purpose, an anilin inkbeing tonnd satisfactory. This ink roller is mounted to rotate on anarbor 114 carried on the end ot' a lever 115 pivoted by a shoulderedscrew 11G to the upper end of a rock arm 11T journaled on a stud screw118 cnaginga post 115) fixed to thebedplate 12. 'lhe said lever 115 isheld in an extended position by a spring 120, coiled about the screw116, its free end engaging said lever 115. The rock arm 117 isoperatively connected with the lug 95 by a link 121 tornied of a rigidwire furnished with a ring at the upper end which engages a shoulderedscrew 122 inserted in saidlug 95, its other end 123 being bent at arrght angle -to pase through a hole in a lug 124 pivoted tothe rock arm1.17.

A signal bell 125 is 'conveniently 'located near the rear of the plate12 and is provided with a hammer 12Gfpivoted to the bed plate at 12T andis'held ina retracted position by a spring 19,8. i

To the outer snrt'ace ot the ratchet plate 5S is attached a gravity belltrip 12S) which swings on a pivot 130, and rests ,against a stop pin131. As the carriage is moved rearwardly the lower end 132 of the saidtrip will engage the heel 133 of the hammer lever and cause thelat-terto strike the bell when released as the carriage passes on. lVhen thecarriage is returned the trip will yield on its center 1230 to permitthe end to pass over said heel.

The operation of the machine is as tollows:-l`he ink roller having beensupplied with a Aproper quantity of ink and a sheet-of paper insert-edbetween the platen and tension plate and carried under the giiide rod,

.the latter is locked against the platen by the lever 85. The operatorthen grasps the operating key F1 and moves said key and attachedtype-bar laterally until the guideiinger 5lis approximately above therecess in the character bar 20 corresponding with the cha acter which itis desired to print, He then depresscs the key carryingthe type bar andframe downward until the type strikes the paper against the platen.relaxing the pressure hc permitsthe spring .20 to vrestore the saidtrame and type barto the initial position. The bar is then movedlaterally by means ot the operating key until another character isselected and printed by depressing the key; andthis process is repeateduntil the alarm bell gives warning that the end ot the line is reached.The carriage movement is controlled'by the lever 9G, the depression otwhich carries the pawl arm 10-1 toi-ward to engage a new notch, thetension ot' the spring 101 being sufficient to re` store thelever 91Sand attached' arm 104 to theirinitial positions and at the saine timemov' the carriage. one step toward the rear.

The lever 90 may be depressed by the finger, which is'the methodemployed to space between words or when no print is required and isalways automati :ally depressed whenever the key 51 operated, bytheengagement therewith ot the pendent lug,` 95. The automatic movementswhich take place when the operating key 51'is depressed are asljfollows:The tirst e tert of the downward move-- v ment of the type bar carnageis to throw the inkinglever and roller to the 'left to leave a clearspace for 'the impression to be `made upon the paper. This is done bythe action of the link 121. which carries the rock larm 11? and attachedlever 115 to the lett, the

ink roller being then entirely out ot' the way by the time the type barcarriage is depressed to the printing plaine. .At the same time the lug95 engages the spacing lever fifi, causing the arm f l't' to rock on itscenter pressed to release the lugltl and the pawl lever 104 lifted outof engagement with the fi. ln a type-writing machine, including a papercarriage and inking mechanism, the comliination with a base and astandard thereon` of a bracket removably attached to said standard, aframe-arm rigidly secured at one end to the bracket, an oscillating Iframe pivoted to said arm, a spring for sai ratchet, thus leaving thecarriage free to be moved either' forward or back with the other hand solong as the pawl arm is kept elevated. When one line is finished theoperalor turns the platen by the line siacing lever 74 to feed thepape', a single epresl `sion acting upon one tooth to give one space,

and when more space is required between the lines the lever given therequired number of dei'iressions or the platen can be turnedindefinitely, and may be used to' feed the paper, for line spacing or toremove it from the roller.

It is obvious that man v changes may be l made in the devices of myinvention as herein` disclosed without departing from the spirit andscopethereof, and l do not wish, therefore, to be limited to the preciseconstruction set forth.

Ilaving thus described my invention I claim 1. ln a typewriting machine,including a papel' carriage and inking mechanism, the combination with abase and a pillar thereon, of a bracket removably secured to the pillar,a frame-arm rigidly` attached at one end to said bracket, an oscillatingframeA fraaie, means for adjusting said spiiing, said means comprising aclam ing screw, a plate 'pivoted on said screw, an a'lug on said plateengagingsaid spring, a type-bar plate slidably mounted in saidoseillatin frame, type-bar pivotally mounted on said type-bar plate,means for rocking said bar 'on its pivots, said rocking means eomprisinlugs extending laterally from oppositesi es of the said bar, keyspivotally attached to-said lugs, a stop carried by said bar and adaptedto limit the movement of the bar in 0th directions upon its centers, andmeans for yieldingly locking said bar at either liniit of its movement.
